When building and populating domain NS a couple of functions are called that append paths to a string list. This string list is then inspected, one item at the time by qemuNamespacePrepareOneItem() which gathers all the info for given path (stat buffer, possible link target, ACLs, SELinux label) using qemuNamespaceMknodItemInit(). If the path needs to be created in the domain's private /dev then it's added onto this qemuNamespaceMknodData list which is freed later in the process. But, if the path does not need to be created in the domain's private /dev, then the memory allocated by qemuNamespaceMknodItemInit() is not freed anywhere leading to a leak.
